OK, wait.. let me make these complex statisitical inferences about your character based on a diverse array of inputs and qualities I have determined are related to life outcomes which I feed into this algorithm I walk around with in my head and then I'll decide if you're a decent person or not....
More about having a stable, high trust society than any individual judgements.
If 1:1000 people in a population are shit, they can still build a great deal of social trust. If 1:100 (or 3:10 where you put it, though it's probably more like 1:5) are shit, trust is going to be much more difficult to build and maintain. Further, any non-homogeneous society experiences faction, though that can be compensated for if they're ethnically very similar and assimilate over time.
interracial
intraracial
For the second part, I'd say lets stay away from Jews for now, since those practices aren't technically criminal, there aren't good sources of statistical information, and all we can do is look at incomplete secondary information that just correlates to their occupation and compensation.
I said it can be compensated for, not that it's natural. Aristotle observed the problem with ethnicity and faction over two millennia ago. Having very different haplogroups exacerbates what was already an issue between similar haplogroups.
